 Posted: Fri Aug 17, 2012 12:17 pm Post subject: Password protection? |
 |
|
Hey,
I was wondering if its possible to do password protection.
Like
lets say
its opening first | Code: | | show_form(PASSWORD) |
And then user needs to enter the password, if he wrote the right password then
| Code: | else
show_form(UDF1) |
I really don't know what to write to get this code,
I hope anyone could help me write it down, Thanks!
Alright so I've used VB few years ago, and I remember that I did the password protection,so I've googled up and found a video showing how to do it again.
The code is:
| Code: | Private Sub Command1_click()
User = "user"
Pw = "pw"
If Text1.Text = User And Text2.Text = Pw Then
MsgBox "Successful Login"
Form2.show
Else
MsgBox "Wrong ID or Password, Try Again"
End If
End Sub |
Commands are very simlar to LUA, but I just don't know how to translate it to LUA.

There is no inputQuery right now (perhaps next version) so for now you need to first show a password box, read out the input and check if it's correct, and if so, show
anyhow, do
| Code: |
form_showModal(formname)
|
to show the form and wait till the user closes it. (If set the "ModalResult" property of a button on that form to something else then mrNone, clicking that button will close the form)
Then read out the text, using control_getCaption(formname_editboxname) or getProperty(formname_editboxname, "Text")
and check if it's valid or not and continue from there (showing a form, or a message saying it's wrong)

You can do this:
1) do not use hotkeys, only set them inside LUA script
2) place all form controls inside panel
3) set panel visibility to false
4) create label and edit controls (for password)
5) if password is correct,
- set panel visibility to true (label and edit visibility from step 4, set to false )
- create hotkeys
6) if password is incorrect - do nothing
most important part:
| Code: |
function passwordeditkeypress(sender, key)
if key ~= '\r' then return key end
if control_getCaption(editPassword) ~= 'secret' then return end
createHotkey(cheat_1,VK_F1,VK_MENU)
createHotkey(cheat_2,VK_F2,VK_MENU)
control_setVisible(labelPassword, false)
control_setVisible(editPassword, false)
control_setVisible(CETrainer_CHEATPANEL, true)
end
control_setVisible(CETrainer_CHEATPANEL, false)
labelPassword = createLabel(CETrainer)
control_setPosition(labelPassword,5,5)
control_setCaption(labelPassword,'password:')
editPassword = createEdit(CETrainer)
setProperty(editPassword,'EchoMode','emPassword')
control_setPosition(editPassword,5,25)
setMethodProperty(editPassword,'OnKeyPress',passwordeditkeypress) |
try cetrainer below.

unless using some external module (some dll), ce lua source alone is not secure anyway 
It may be more viable to protect some content the script to be handle.
Suppose I want to protect aob string I input in DaSpamar's Easy trainer.
I would encrypt the aob by some algorithm with a key.
The key is generate by hashing the cheat maker's input of user_id and password.
Then the cheat user virtually must input the same user_id and password, to correctly de-crypt the aob.
The key point is, there are no need to store key , user_id and password in the source, even the script is not secure.

Pointless can be seen as plain in memory.
Server-side works the best.
I've taken cheat engine trainers few steps forward  .
(Pay attention that was before I knew lua scripting)

You are never going to create any method of security that can't be reversed / undone, especially with a language like Lua. No matter what you do, people can find your aob's and such. Not to mention, Cheat Engine is open source, they can change how Cheat Engine handles aob's and print them out to a file or something if they wanted and run your trainer through their own CE.
No matter what you come up with, there will be a way to undo it and see your code.

Yeah...even if you managed to host your trainer on your own server and issue client copies to end-users with ID/Passwords, they can still scan for changes to see what your trainer is doing on their own systems.
There is little point in protecting a trainer unless you are hosting it and it is being used for online games.

I agree you two.
Yet, increasing security level do have a effect on minimizing the intersection of set of people having the required hacking skill and set of people having the time,energy and interest to break a trainer, hopefully to an empty set

There are a lot of other ways people can monitor what your trainer is doing with little to no effort or skill. |
again, I agree, if the knowledge is not count as skill.
but you can ask DaSpamar if the security effort on his current trainer is a paper tiger
Anyway, it is going off-topic, sorry~

@panraven you're mistaken this is not my trainer security, this was a question in my early days of lua scripting (2 and half years ago..).
I use db to fetch user data and show specific data for each user, if you want I can message you with my trainer d/l.
If someone wants to break my trainer, I have no problems with it, nothing will prevent it if he really seeks to.
